Definitions

  • This invention relates to a process by which it is possible to make a sharp-angled indentation on hollow tubes without removing any matrial, maintaining a constant thickness of tube and also without deforming the external diameter and conserving the fibre orientation of the metal.
  • the purpose of this invention is to resolve these problems by offering a process that makes it possible to make sharp-angled indentations on hollow tubes, without removing any material.
  • the process used in this invention is characterised by the fact that the riveting head of a riveting machine of this type is replaced by a former adapted to the profile of the indentation to be made and in particular to its sharp angle.
  • the tube on which indentations are to be made is inserted between the former and the fixed half-clamp and the pressing devices are activated, causing movement of the spindle, in order to allow indentations to be made in the tube.
  • the riveting machine is a riveting machine with an epicycloid mechanism and a spherical joint.
  • the indentation former is subjected to a complex movement that can be broken down into a translational movement and an orbital movement.
  • the spindle of the riveting machine is fitted with a holding-down clamp, the front part of which secures the tube in which indentations are to be made and holds it tightly against the fixed half-clamp.
  • Another characteristic of the invention is that rotation movement of the indentation former is prevented by means of a stabilising device.
  • the depth and the surface area to be obtained determine the power of the riveting machine.
  • the invention also relates to a hollow tube produced by means of the process described above.
  • Such a tube is characterised by the fact that it has sharp-angled indentations which have been made without removing material, maintaining constant tube thickness.
  • FIG. 1 is a perspective view of a tube as according to the invention
  • FIG. 2 is a section through this tube
  • FIG. 3 is a schematic section of the riveting machine used in this process
  • FIG. 3 a is a schematic section of FIG. 3 along axis A—A;
  • FIGS. 4 and 4 a , 5 and 5 a , 6 and 6 a show three examples of indentation formers as sections and views from below, respectively.
  • the surface of the tube ( 1 ) has a series of indentations ( 2 ) of a determined profile.
  • the indentations ( 2 ) have sharp angles ( 3 ) and are made without removing material so that the thickness of the tube remains constant.
  • the riveting machine ( 4 ) used to make indentations in the tubes ( 1 ) is a machine with an epicycloid mechanism and a spherical joint, which is a well-known type of machine and which, for this reason, will not be described in detail in the context of this statement.
  • This machine is equipped, firstly, with a fixed half-clamp ( 5 ) and secondly a moving half-clamp or holding-down device ( 6 ) fixed to the head of the machine ( 4 ) by means of a screw ( 7 ) in conjunction with sleeves or springs made of rubber.
  • the two parts ( 5 , 6 ) have grooves ( 8 , 8 ′) located opposite each other in order to hold the tube ( 1 ) in which indentations are to be made.
  • the machine ( 4 ) is also fitted with a former ( 9 ) fitted to the nose of the same.
  • FIGS. 4, 4 a , 5 , 5 a , 6 and 6 a show examples of former profiles ( 9 ) which can be used according to the type of indentation to be produced.
